HINGE.

Specification 01 Letters Batent.

Patented May 12,1914.

Application filed August 23', ms. Serial No. 788,292.

To all whom it may concern:

Be it known that I, SAMUEL Soss, a citi-;

zen of the United States, and residing at- New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Hinges, of which the following is a specification, suchas will enable those skilled in the art to which it appertains to makeand use the same.

This invention relates to hinges for doors, gates, window sashes andother articles and particularly to what are known as invisible hinges,or hinges which cannot be seen when the door, gate, sash or otherarticle to which the hinges are applied is in a, closed position, andthe object of the invention is to provide an improved hinge or hinges ofthis class which are simple in construction and by means of which thedoor, gate, sash, or other article may be given any desired throw, ormay be swung through an arc of any desired extent according to theconstruction of the hinge or hinges, which construction may be regulatedor modified as may be desired.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawin forms a part, in which the separate parts0 my improvement are designated by suitable reference characters in eachof the views, and in which- Figure 1 is a view showing a hinge madeaccording to my invention, applied to a door, the door being open andonly part of the door and part of the door frame being shown ;--F-1g. 2a sectional view showing the door closed and showing the door frame anddoor and the butts of the hinges in section ;--Fig. 3 a cross section onthe line 33 of Fig. 1, and on an enlarged scale ;--Fig. 4 a front viewshowing a modified form of hinge, and showing it open, and ;-Fig. 5 aperspective view of one link member used in the construction of myimproved hinge, and a number of which are employed.

In the accompanying drawing I have shown at a a part of a door frame andat be, part of a door and at c, in Figs. 1 to 3 inclusive, one of myimproved hinges in the preferred form.

In the construction of my improved hinge, as shown in Figs. 1 to 3inclusive, I ro videtwo hinge butts d which are preferably of the usualform and comprise yoke'shape'd body portions adapted to be countersunkin the door frame and door and prow'ded with screws e whereby the hingeor hinge butts are secured in position in the door frame and door.

The hinge butts d may be stamped from sheet metal or cast, but saidhinge butts, when too great strength is not required, are preferablystamped from sheet metal, and the central yoke-shaped body portions ofSEl-ld hinge butts are provided slightly inwardly of their correspondingside edges with inwardly set flanges d which extend the full length ofthe body portions of said hinge butts, and the correspondin end ortionsof the flanges (Z are provide with ongitnd'inal slots d which extend aproXimately from a third to a half of the length of said flanges.

The movable part of my improved hinge or hinges consists of a togglelever construction 0 made up, in the form of construction shown. ofthree pairs of link members, a central pair and two side pairs, saidside pairs and central pair being connected at a, and one link member ofeach side pair is pivoted to one of the flanges d oi the butts at o, andthe other link members of the side pens are provided with pins 0 movablein the slots d.

All the link members used in the construction of the movable parts of myimproved hinge or hinges are arc-shaped in form, or formed on the arc ofa circle, and the curvature of the inner link members a is referablyslightly less than the curvature o the outer link members a, and inpractice, the inner link members 0 are also preferabl made slightlyshorter than the outer lin members 0', but this is immaterial in theoperation of the hinge, and in the case of a light hinge, in which thelink members are made of thin material, the curvature of the inner linkmembers need not necessarily be greater than the curvature of the outerlink members.

In the preferred form of construction, as shown in Figs. 1 to 3inclusive, the end poror side pairs are flattened, as shown at (For bentat an angle to the body portion of said link members so that said endswill rest flatl on the flanges cl of the butts, and this constructionwill'facilitate the operation of end projections di through which arepassedtions of the-link members of the outer pairs the hinge especiallywhen said flanges are made straight and parallel with the side edges ofsaid butts.

The link members of the separate pairs of links, in the toggle leverconstruction are connected at 0 in the usual manner, and in theaccompanying drawing, only three of said pairs of said link members are.shown, but it will be understood that the number of pairs of linkmembers used in constructing the toggle lever part of my mproved hingeor hinges may be varied, or increased, and with the construction shown,the extent of the throw or swing of the door, gate, sash or otherarticle to which the hinge or hinges are applied or the extent of theare through which the door or other article will swing, will depend uponthe curvature of the link members which make up the separate pairs oflinks in the toggle lever construction, or, in other words, the extentof the swing or throw of the door or other article, or the extent of theare through which said door or other article swings will be increased,as the curvature of the link devices which make up the separate pairs oflinks in the toggle lever construction is increased, but it must beunderstood, of course, that this increased curvature of the link devicescannot be carried beyond a certain definite point.

In Fig. 4, I have shown a modified form of hinge in which I substitutefor the-straight flanges or connecting plates (Z of the hinge butts d,curved flanges or connecting plates (i which may be formed in, orsecured in. the butts d in any desired manner, and in which the slots (Zare formed, and with this construction, the end of the links of the sidepairs of the toggle lever construction are not flattened, as shown inFigs. 1 to 3 but said links maintain their curvature to the outer endsthereof, and the curvature of the flanges or plates 03 corresponds withthat of the link members, and in this form of construction, a washer fis employed between the end of one of the side link members and thecorresponding flange or plate d of one of the butts (Z, and a similarwasher f between the diagonally opposite end of the corresponding otherside link member, and the flange or plate d of the other butt, thisconstruction being necessary in order that the parts of the hinge mayfold completely together when the door, gate, sash, or other article isin a closed position.

My improved hinge may be used whenever it is necessary to connect aswinging device or article with a stationary support, and isparticulaniy adapted for use in all cases where the swinging device isnot of great weight, and it will be understood that any desired numberof my improved hinges may be used in connection with a single swingingdevice and stationary support, and it will be also understood that myimproved hinge or hinges may be made of any desired strength, thestrength depending on the weight and size of the hinge or hinges, andthe material employed.

From the foregoing descriptionit will be seen that with the constructionshown and described, the movable parts of the hinge or toggle leverconstruction are entirely folded within the butts d when the door, gate,sash or other article to which thehinge or hinges are applied is in theclosed position, and my invention is not limited to any particularconstruction of the butts d, or method of making the same, all that is;-necessary in.

this connection being that said butts be so formed that when theseparate parts of the hinge are folded together the toggle leverconstruction employed will be entirelyv inclosed in the space within thebutts and, if desired, the body portions of said butts may be madebox-shaped in form in cross section, or the sides thereof may be closedin, and other changes in and modifications of the construction describedmay be made, within the scope of the appended claims, without departingfrom the spirit of my invention or sacrificing its advantages, andalthough I have shown and described my improvement as applicable tohinges only, my invention is not limited to this use, and the same maybe applied or used in the construction of gates, in which form. the parta would represent a gate post and the part 7) with the toggle leverconstruction 0 the gate and the gate wouldopen and close in the samemanner as the hinge, the movement of said gate in opening and closingbeing in a curved line, or in the arc of a circle, and my invention mayalso be applied to other uses and for other purposes. It will also beseen that the toggle lever construction which connects the separate buttmembers of my improved hinge is arc-shaped, both in horizontal. andvertical section when expanded and also when collapsed, and, in theoperation of expanding and collapsing the said toggle leverconstruction, the separate pairs of link members that make up saidtoggle lever construction all move in a curved or arc-shaped plane, thismovement resulting from the fact that the separate pairs of link membersare connected end to end in the manner of other devices of this class.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is l. A hinge comprising two butt membersadapted to be countersunk in a stationary support and a swinging device,said butt members being connected by a toggle lever constructionconsisting of a plurality of pairs of links formed on the arc of acircle, one end of one link of the side pairs of the toggle leverconstruction having a pivotal connection with the butts, and the corresponding ends of the other links of the side pairs of links of thetoggle lever construction having a sliding mnncction with the but-ts. I

A hinge comprising two butt members adapted to be countersunk in astationary support and a swinging device, said butt members beingconnected by an arc-shaped toggle lever construction composed ofseparate pairs of links formed on the arc of a circle.

3. In an apparatus of the class described,

a stationary member and a swinging member connected by a toggle leverconstruction composed of separate pairs of links formed on the arc of acircle and adapted to be expanded and folded in an arcuate path.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 22nd day of August1913.
